Dawson Granade loves Fort Worth. His shirt from a local barbecue joint reads “Life’s too short to live in Dallas.” Twice a day, six days a week, Dawson piles visitors from Chicago, Poughkeepsie, and Tokyo into his Suburban and tools around town, spooling out Fort Worth’s history as he negotiates traffic and indicates sites of historical note. It is, he said, “the best goll-darn tour in Texas.”
